Definition : A usually benign tumor composed of cells which arise from chondroblasts or their precursors
and which tend to differentiate into cartilage cells. It occurs primarily in the epiphyses
of adolescents. It is relatively rare and represents less than 2% of all primary bone
tumors. The peak incidence is in the second decade of life; it is about twice as common
in males as in females. (From Dorland, 27th ed; Holland et al., Cancer Medicine, 3d
ed, p1846) [MeSH];
